Convergence Zone snow hits I90

My son is turning back from his trip to Snoqualmie Pass for his snowboard lesson. The reason....too much snow and chains are required. The convergence zone has moved south and is now aligned nearly NW-SE...with the heaviest amounts aligned on I90 at and west of the Pass. The radar shows the story...and look at the cam up there--snowy driving. Convergence zones can greatly enhanced the snow at Stevens or Snoqualmie...depending exactly on how they set up. Outside of the convergence zone, some of you getting bright sunshine (see high res sat picture).

Yeeehaw! We've had another 4" so far here east of North Bend. It's still coming down lightly. That's on top of the almost 6" we received on Wednesday. Even yesterdays sunshine didn't melt much of it. My garden is freaking out!

It was blue sky and sunny at Lake Stevens this morning, then around noon it all went dark. :)

It was snowing here a few minutes ago, lightly, but now it has stopped.

I am taking a trip across the pass tomorrow afternoon, so I'm keeping a close eye on the road conditions up there. I hope it's not too bad, but it'd still be nice to put my snow tires that are on my subaru to good use.

There's slush (freezing rain?) falling from the sky at sea level near Shilshole. The winds are really picking up, and a thick wall of dark clouds is advancing East. The trees are really swaying and my dog is looking nervous.

I have never seen hail come down as hard and as much as it is right now on Union Hill in Redmond. Its crazy! Its like a white-out, but with hail. And of course, its coating everything. I walked outside and it stung the skin bad. Very, very loud. Looks cool though :)

On Whidbey in Greenbank looking over at Pt Townsend to Ebeys on Island. Huge black cloud with front blotting all out in its path coming down Admiralty Inlet. Have been gale force winds here since about 6 am with no letup. Hail hail the gangs all here. :-)

South Hill Puyallup:Sunny and windy most of the day. It got really dark around 1400, ice pellets, snow and wind for 5 minutes, then back to sunny and windy. The wind is cold, but all in all a nice day.

Styrofoam 'snow' total about 1/2 inch Crown Hill 335ft. The expected one clap wonder thunder, which was much closer than usual. Often it seems to be out over Bellevue or the foothills, but this was in the city.

Cleared up nicely right after and had some nice moonshine during snowball fight with the kids.

Location: Snoqualmie Ridge - Looks like the convergence zone is moving back north and will be right between I-90 and Bothell (522). We picked up a quick 2-3" a couple hours ago and saw a flash of lightning and heard thunder.

I`m not sure about the CZ moving back north. Looks like it`s continuing it`s track southward with just an area of showers passing near the Seattle area currently.

Also... looks like we may be done with snow tonight here in the central/north sound, though some spotty showers could still be seen. But now the main focus will be the cold dry air and cold over night lows. Looks like we dip down into the 20`s the next few nights.
